Abstract
The utility model relates to an appliance or equipment used for the reduction of fracture, particularly a screen plate for skull rehabilitation and a screw for self tapping and self drilling. The utility model comprises a screen plate and screws, wherein the screen plate comprises connecting points, a connecting part which is used for connecting each connecting point and formed screen meshes. The screws are of sunk screws, and counter bores which are used for the screws to penetrate are arranged on the connecting points. The utility model adopts the sunk screws and the counter bores corresponding to the sunk screws, the sinking head of the screw can be hidden in the counter bores and can not protrude above the screen plate, and the abrasion to scalp can not be caused. The rigidity can not have obvious difference no matter which direction the screen plate bends to, the utility model has astatism when the utility model has multidimensional molding, and the utility model has easy and convenient operation.
Description
[technical field]
This utility model relates to utensil or the equipment that is used for synthetism, and particularly a kind of skull reparation is with web plate and self tapping self-drilling screw.
[background technology]
In the prior art, the method for repairing defect of skull comprises: adopt the titanium plate, silk thread, stainless steel silk or screw are fixed.Wherein, the titanium plate is firmer, good biocompatibility, but it is moulding relatively poor, in operation, be difficult to repair plate and be moulded the shape that matches with the skull surface shape according to skull 2 damaged situations, so generation covering imprecision or edge wing rise and damage scalp easily, in severe case, cause infection to need operation once more., the silk thread fracture can take place and cause the restoration displacement as immobilization material with silk thread, needs are operation once more.The skull holostrome need be bored thoroughly with fixation with steel wire, operation need be deep into intracranial, and the danger of injured brain tissue is arranged.May produce intracranial hematoma after the operation and need operation once more, and can stay bigger steel wire knot under the scalp, scalp is produced pessimal stimulation.
So at present methods that adopt metallic plate and screw fit to use more: but because metallic plate all is a monoblock flat board, the approximate hemispherical shape that it will be bent to skull in operation is relatively more difficult, and the periphery that is shaped creases easily, outward appearance is undesirable after causing skull repairing, the scalp that can wear and tear when serious causes infection; Simultaneously, a part that hammers into the screw of metallic plate and lamina externa cranii can be exposed at the outside of metallic plate, the scalp that still weares and teares easily, and as shown in Figure 1, wherein, 1 is metallic plate, 2 is screw.Also have a kind of way on metallic plate, to dig out the circle of a lot of regular shape, ellipse, rhombus or orthogonal hole, thereby form a reticular lamina, but in use still there is the moulding problem of difficulty, especially when the needs angle of bend is big, will present rough pleat Zou on the metal otter board, influence repairing effect, also have the situation of the outstanding wearing and tearing of screw scalp simultaneously.
[summary of the invention]
The purpose of this utility model be to provide a kind of metallic plate easily moulding and screw can not wear and tear the skull reparation of scalp with web plate and self tapping self-drilling screw.
The technical scheme that its technical problem that solves this utility model adopts is: the skull reparation comprises web plate and screw with web plate and self tapping self-drilling screw; The connecting portion that comprises junction point on the described web plate and be used for each adjacent junction point is coupled together, and the mesh that forms; Described screw is a sunk screw, and described junction point is provided with the counterbore that passes for screw.
When each junction point was positioned at same plane, adjacent several junction points were arranged in regular circular, rhombus, rectangle.
Connecting portion between the adjacent junction point is the arc of rule, and is multi-direction radial arrangement.
Described junction point and connecting portion are one.
Described web plate is made by titanium or Nitinol.
The beneficial effects of the utility model are: 1. adopt sunk screw and counterbore corresponding with it, the countersunk head of screw can be hidden in the counterbore, can not protrude on the web plate, can not cause wearing and tearing to scalp.2. junction point queueing discipline, connecting portion is regular arc, multi-direction radial arrangement, makes web plate no matter to which direction bending, and its rigidity does not have notable difference, and it is non-directional when moulding to carry out multidimensional, operates easy and convenient.3. titanium metal material has stable chemical performance, good biocompatibility, intensity height, nonmagnetic, light weight, does not influence advantages such as X ray, film making and MRI inspection.Nitinol has better shape memory except that having above-mentioned advantage, can be formed by simple processing according to skull situation scene by the doctor in operation.

[specific embodiment]
With specific embodiment this utility model is done to set forth further with reference to the accompanying drawings below.
To shown in Figure 6, the skull reparation comprises web plate 1 and the screw 2 made by titanium or Nitinol with web plate and self tapping self-drilling screw as Fig. 3.Comprise junction point 11, connecting portion 12 and mesh 13 on the web plate 1.The junction of each mesh 13 forms junction point 11.Connecting portion 12 couples together each adjacent junction point 11.A plurality of adjacent junction points 11 and connecting portion 12 surround mesh 13.Wherein, when each junction point 11 was positioned at same plane, adjacent several junction points 11 were arranged in regular circular, rhombus, rectangle or other polygon, and the connecting portion 12 between the adjacent junction point 11 is the arc of rule, and were multi-direction radial arrangement.Like this, straight line connecting line between arc connecting portion 12 and each two junction point 11 does not coincide, make web plate 1 when being subjected to external force and producing distortion, in the bending that produces three-dimensional, do not have tangible directivity when reversing, can not produce the fold that is difficult to eliminate with warpage.Simultaneously, connecting portion 12 can be the regular arc of multiple class, makes space length between two junction points 11 not be subjected to the constraint of other junction point 11.
Be provided with the counterbore 111 that passes for screw 2 on each junction point 11, in operation, according to circumstances be chosen in and settle screw 2 in the part or all of counterbore 111, so not only can guarantee the fastening effective of screw 2, avoided the stress concentration at junction point 11 places simultaneously.But screw 2 adopts self tapping from the sunk screw that bores, and makes operation technique more convenient.Simultaneously, after screw 2 installed, its countersunk head just entirely attached, is hidden among the counterbore 111 on the junction point, the patient's of can not wearing and tearing scalp.As shown in Figure 2.
